求一导出EXCEL方法
小弟初学者,现在做一网站遇到需要把数据导出EXCEL的功能请路过的前辈指点一个给力的方法,最好有案例源码的~ 谢谢 --------------------编程问答-------------------- http://blog.csdn.net/wonsoft/archive/2008/11/16/3311769.aspx --------------------编程问答--------------------

string colHeaders= "", ls_item="";
int i=0;
//定义表对象与行对像，同时用DataSet对其值进行初始化
DataTable dt=ds.Tables[0];
DataRow[] myRow=dt.Select("");
// typeid=="1"时导出为EXCEL格式文件；typeid=="2"时导出为XML格式文件
if(typeid=="1")
{
//取得数据表各列标题，各标题之间以\t分割，最后一个列标题后加回车符
for(i=0;i<dt.Columns.Count-1;i++)
colHeaders+=dt.Columns[i].Caption.ToString()+"\t";
colHeaders +=dt.Columns[i].Caption.ToString() +"\n";
//向HTTP输出流中写入取得的数据信息
resp.Write(colHeaders);
//逐行处理数据
foreach(DataRow row in myRow)
{
//在当前行中，逐列获得数据，数据之间以\t分割，结束时加回车符\n
for(i=0;i<row.ItemArray.Length-1;i++)
ls_item +=row[i].ToString() + "\t";
ls_item += row[i].ToString() +"\n";
//当前行数据写入HTTP输出流，并且置空ls_item以便下行数据
resp.Write(ls_item);
